Okay. I think I might vote
Form toDay - since he isn't dead my guess is that he is actually a wolf and that is why he's still alive. And if he isn't a wolf then it's at least quite likely that he is a cobbler, given the way he behaves. And even if he is an ordo he's at least a confusing one and I feel more at ease with not having to ponder about him..
Other possibilities could be
Nog or
Fea or
Nilp (because he's the most wolvish of all the under-the-reindeer people).
By the way, it has been nice to see more of both
Kath and
Shasta. I think I have more to think about both of them. At the moment
Kath feels innocent.
EDIT: x-ed since Brinn
